This invention relates to-means for feeding welding material to awelding appliance or feeding solder to a soldering tool.

The invention may be embodied in a variety 0f forms and is illustratedby way of example as being applied to a soldering tool and as eingdesigned to feed solder in a wire form to said tool at the point of use.An object ofthe invention is to provide an attachment for the purposestated which may be conveniently attached to soldering devices orwelding tools already on the market and which will be provided withsuitable manually operable means for conveniently feeding the solder orwelding material to the point of use, as required, during the operationof the tool.

Another object of the invention is toprovide improved means foradjusting the delivery portion of the solder feed device whether in aposition wherein it is'lo cated close to the soldering portion of thetool; or in a position where it is farther removed from the solderingportion of the tool so that the tool may be heated without melting thesolder at a time when not required for use.

Other objects, advantages and features of invention may hereinafterappear.

Referring in detail to the drawing, wherein my newly invented attachmentis shown mounted upon a well known type of electrically heated solderingtool, the cylindrical body, portion 10 of the tool is provided with ashank portion 11, a handle portion 12 and a soldering portion 13 whichterminates in a conical tip or applicator portion 14.

Referring now more particularly to the attachment wherein the inventionconsists, the frame 15 is provided with a side plate or standard portion16 which extends lengthwise of the-tool and radially from the axisthereof, and a base portion 17, said portion 17 being desirabl a flangewhich extends lat- .erally from the side plate 16. Near the junction ofsaid flange 17 with said plate 16, said plate is provided with apertures18 through which extend the clamping members 19. Said clamping members19 each consist preferably of a split ring which is provided at eachside of the split portion thereof with an apertured ear 20, clampingbolts or screws 21 being passed through said ears and having screwed onto them the nuts 22. The ,clamping rings 19 are preferably .oonstructedto enclose the body of larger diameter than the body 10 of the solderingtool, thus roviding room for interposing a layer 24 o asbestos or otherheat-insulating material between each of said rings and the body of thesoldering.tool. The up er portion of the sheetmater'ial, of which t eplate 15 is preferably formed, is

arched or bent over as shown in Fig. 3 to form, means to adjustablysupport the guide 25 for the wire solder 26 which is fed from a reel 27,said reel being rotatably supported v in any desired manner as, forexample, by a pivot rod 27a which is mounted upon the main frame 15of-the attachment. Said guide 25 has a rotatably adjustable curved spout28 mounted therein, the adjustment of said spout 28 being efiected bymeans of a rod 30 which is so bent as to avoid interfering with otherparts of the device, and which is providedwith an operating handle 31positioned for convenient adjustment by means permit a solder wire 26 tobe conveniently fed therethrough and said spout is rotatably mounted soas to be adjustable by means of the rod 30 to and from a position forbringing the delivery portion thereof into close proximity with the tipportion 14 of the tool.

The preferred means to support the spout 28 in order to provide arotational adjustment thereof is shown in detail inFigs. 1, 2 and 6.Referring more particularly to these views, the arched or bent overportion 25 of the frame side plate 16 is arranged to form a clamp tosecure in place a bearing sleeve 268 within which is rotatively fittedthe hearing or shank portion of the spout 28. Said bearing sleeve 26s isgripped in place by means of the clamping bolt 26?) and clamping nut 26%with which the clamping member which has been described is provided. Asshown in section in Fig. 2 the adjusting arm or rod 30 is provided witha downwardly directed end portion 30a; which is flattened as shown andis welded or otherwise secured to the shank portion of the spout 28.

Between the guide 25 and the reel 27 combined guiding and feeding meansare provided through which the solder wire 26 is led.

These last mentioned means comprise a pair of cooperating dog-carryingelements, namely, a rear dog-carrying element 35 and a frontdog-carrying element-45. Said element 35 is pivotally mounted upon andmoves with a bell crank lever 36 which is pivotally supported at 37 andwhich is provided with a downwardly and rearwardly extending operatinghandle 38 positioned to be-convenient ly moved by a finger of the handwith which the operator holds the tool. Said element 35 is shownprovided with a headed guide stud 39 which projects through a slot 40provided in the frame plate 16. A spring 41 has one end connected withsaid element 35 and its other end connected with the side plate 16, saidspring being thus positioned to retract or move rearwardlv. the element35 after it has been moved forwardly by means of the handle 38. Saidelement 353s also provided with a dog 42,- the free end of which engagesthe lower side of the solder wire 26 in such a manner as to cause saidwire to be fed toward the point of use whenever the handle 38 isoperated. Said dog 42 is provided with a re tracting spring 43 which maybe attached to attachment. Said element 45 is provided with a dog 46 thefree end of which is positioned to prevent'retrograde movement of thesolder wire 26, said dog being held in its operative position by. meansof a small retract ing spring 47 which is shown attached to the pivotalsupport 48 of the dog.

In order to cause the dogs 42 and 46 more efliciently to perform theirfunction the dog 42 is shown provided at its free end with a notch 42%adapted to engage the solder wire 26 and the dog 46 is provided with alike not-ch 4611, which performs a similar function.

The tool is shown provided with the usual electrical connection 50m andterminal plug 51w.

In Figs. 7 and 8 is shown a modified form of the invention wherein partswhich remain the same as in the form first described, have similarreference characters applied to them.-

In these views, however, the upright frame plate 47 is modified to adaptit to have piv-- otally attached thereto by means of apivot screw 47a, arocking plate or frame 48. Said plate 48 is provided with a dog-carryingportion 45 like that shown in Fig. 1, and also has a spout 28sec'uredthereto by means of a bent over portion 48?) thereof, the clamping screw480 being used to hold said spout 28 in place. At its inner or rearendsaid plate 48 is'provided with an extension 48m to which is secured theupper end of a tension spring 488, the lower end of said spring beingsecured to the plate 47. By this arrangement the spout 28 is normallyyieldingly maintained with its delivery end in spaced relation to theapplicator portion 14 of the tool as clamping bolt 54 having a nut 55screwed on to the end thereof.

One end of said feed lever 50 is twisted to form a finger hold 60 andthe other end of said lever is pivotally connected with one end of alink 61, the other end'of said link being adjustably secured to thefeeding device 65 by means of a clamp or holding device 66 which isprovided with a clamping screw or set screw 67 adapted to be screweddown upon the link 61 to secure it in the adjusted position.

Said feeding device 65 is of the nature of a housing which is adapted toenclose and guide the wire solder as it is fed from the reel 27. Theonly connection between the housing plate 65 and the rocking plate 48 isby means of a pivot stud 70 which extends across the space between thetwo sides of said housing plate 65 and then projects beyond said plate65, as viewed in Fig. 7, the far end portion of said stud 70 extendingthrough'a, slot 71 in the rocking plate 48 and then being provided witha head which keeps it frombeing withdrawn from saidslot, this stud beingformed and arranged like'the stud 39' shown in o the lower portion ofthe housing plate 65 is connected one end of a spring 70a; the

other end of said spring being connected to the extension 48% of theplate 48;] Said spring 70m normally maintains the housing plate 65 ofthe feeding devicein the position shown in Fig. 7 with the pivot stud 70thereof engaging the rear end of the slot 71, but the operator mayoperate the lever against the opposition of said s ring and may thereby,throughthe'action 0 dog 68d feed the wi're solder to-and through theguide spout 28.1 When the finger hold of the lever 50 is 'sulficientlyretracted to bring. the

.stud 70 againstthe forward end ofslot 71,

farther movement of said lever 50 will. tilt the plate 4=8upon its pivot47a and will thereby ;bring the delivery portion of the spout 2'8 closerto the applicator portion 14 of the tool, thus bringing the end-of thewire of solder against the part 14 of the tool and causing it to befused and supplied vfor use when lever 38 is given but a slightoperative move 'ment the-effect will be to feed forward the wire solderwithout affecting the position of thespout 28, but if said lever issufficiently moved it will-rockthe-spout upon its trans- I I verseaxisand bringthe delivery end thereof closer to the applicator portionof the tool. Hence if said-operating leverbe held back by the finger aconsiderable' extent and, While so held back, be repeatedly moved shortdistances the effect willbe to move thedelivery portion of thespouttoward and from the 3P1 plicator portion of the tool withoutadvancmg the wire solder; but if said lever be repeatedly moved'shortdistances from ltS.ll1l-.'
